Answer:

С.

Step-by-step explanation:

From the options provided the only one that represents a proportional relationship was The cost of purchasing a box of socks for $1.75 per sock plus $2.15 for the box. This is because the total cost of the boxes depends on the number of socks that are bought since every pair of socks that are bought comes with a box which causes the total costs of the boxes to increase. Therefore, the number of sock pairs and the number of boxes has a proportional relationship.

Using cosine rule,
x^2=y^2+w^2-(2yw x cos X)
x^2=4.5^2+5.7^2-(2x4.5x5.7xcos 155)
x^2=99.2336
x=root over 99.2336
x=9.96 cm.
I hope this helps!
